FAG super precision Angular contact ball bearings B718 series can support axial forces in one direction as well as radial forces. Spindle bearings B718 series used in an O or X arrangement can support axial forces in both directions and moments. Bearings in a tandem arrangement can only support axial loads in one direction
FAG super precision Angular contact ball bearings B718 series are available with a contact angle α = 15° (suffix C) or α = 25° (suffix E).
FAG super precision Angular contact ball bearings B718 series of universal design can be fitted in any arrangement or combined in various sets without any loss of performance. The position of the pressure cone is marked on the cylindrical surface of the outer ring. The preload is altered by mounting and the operating conditions.
FAG super precision Angular contact ball bearings B718 series have solid window cages made from hard fabric (suffix T). The cage is guided on the outer ring
